You use Spinnaker to deploy your application and have created a canary deployment stage in the pipeline. Your application has an in-memory cache that loads objects at start time. You want to automate the comparison of the canary version against the production version. How should you configure the canary analysis?

• A.Compare the canary with a new deployment of the current production version.
• B.Compare the canary with the existing deployment of the current production version.
• C.Compare the canary with the average performance of a sliding window of previous production versions.
• D.Compare the canary with a new deployment of the previous production version.

You are on-call for an infrastructure service that has a large number of dependent systems. You receive an alert indicating that the service is failing to serve most of its requests and all of its dependent systems with hundreds of thousands of users are affected. As part of your Site Reliability Engineering (SRE) incident management protocol, you declare yourself Incident Commander (IC) and pull in two experienced people from your team as Operations Lead (OLJ and Communications Lead (CL). What should you do next?

• A.Look for ways to mitigate user impact and deploy the mitigations to production.
• B.Contact the affected service owners and update them on the status of the incident.
• C.Establish a communication channel where incident responders and leads can communicate with each other.
• D.Start a postmortem, add incident information, circulate the draft internally, and ask internal stakeholders for input.

You support an application deployed on Compute Engine. The application connects to a Cloud SQL instance to store and retrieve dat a. After an update to the application, users report errors showing database timeout messages. The number of concurrent active users remained stable. You need to find the most probable cause of the database timeout. What should you do?

• A.Use Cloud Security Scanner to see whether your Cloud SQL is under a Distributed Denial of Service (DDoS) attack.
• B.Use Stackdriver Profiler to visualize the resources utilization throughout the application.
• C.Check the serial port logs of the Compute Engine instance.
• D.Determine whether there is an increased number of connections to the Cloud SQL instance.
